Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697982, here are decompositions:

5 + 8697977 = 8697982
11 + 8697971 = 8697982
113 + 8697869 = 8697982
131 + 8697851 = 8697982
149 + 8697833 = 8697982
173 + 8697809 = 8697982
179 + 8697803 = 8697982
191 + 8697791 = 8697982

Showing the first eight; more decompositions exist.
